How will you handle grammatical inflections?
Which is the past tense of flap: flapped, flapd or flapt?

suffixes? Do gentleman and handyman have the same ending or not?

How is word compounding handled? If you compress
"shue" to "shu", then how do you spell shoebox: shubox or shuebox?

Will you provide distinct spellings for homonyms,
either in a few cases (tu/too/tew), or more generally?

How do you handle words that are frequently pronounced
without stress, (the, of, and, can, etc.)? Do you have
more than one spelling (dhi/dhuh) depending on stress? If not, do
your
spellings represent the stressed or unstressed form?

Can your system handle English interjections, which
often don't follow the usual rules: duh, eh, uh-huh, brr, psst?

Can your system handle words with foreign sounds, such
as loch and contretemps?

Will you allow alternate spellings of words with
dialectal
variations, or will there be a single standard spelling of such
words?And if there is to be a standard spelling, how is it chosen?

Is your system capable of handling potential new words,
at least ones which fit normal English word patterns? Or does it
depend on accidents of the present distributions of words?

If your system requires diacritics, how difficult will
it be to use them, both visually and practically? For instance,
accented i's are hard for some people to read, and many reasonable
combinations, such as an e with a tilde, are not present in many fonts.
